Abstract
This study aimed to utilize fly ash, a solid waste product from coal combustion in the fertilizer industry, as an alternative coagulant for wastewater treatment. Fly ash was activated using H₂SO₄ with varying concentrations (2%, 4%, 6%, 8%) and coagulant dosages (2 ml, 4 ml, 6 ml). The effectiveness of the fly ash coagulant in reducing Total Suspended Solids (TSS) and Chemical Oxygen Demand (COD), as well as its effect on wastewater pH, was analyzed using the jar test method. The results showed that the fly ash coagulant effectively reduced TSS and COD levels, with the most significant reduction occurring at a dosage of 4 ml and an H₂SO₄ concentration of 8%. Under these conditions, TSS decreased by 82.35% (from 0.79019 kg/ton to 0.13945 kg/ton) and COD decreased by 72.72% (from 0.02045 kg/ton to 0.00558 kg/ton). Correlation analysis indicated a strong relationship between H₂SO₄ concentration, coagulant dosage, and the reduction of both TSS and COD. Although effective in reducing TSS and COD, the fly ash coagulant caused a decrease in wastewater pH due to its acidic nature. Further research is needed to mitigate the pH reduction following the application of the fly ash coagulant. Keywords: Fly ash; coagulation; wastewater; H₂SO₄ activation; Total Suspended Solids (TSS); Chemical Oxygen Demand (COD); pH; jar test; fertilizer industry.
